' Application filed April 29, 1922. Serial no. 557,413.

- an improved tool of this character having means whereby the grip orhandle. portion may be readily and. positively adjusted to varioussizes.. Another object is to provide a tubular hand grip in a tool ofthis class and a further object is to provide an improved device whichwill be self supporting upon the hand of the husker entirelyindependently and free of all straps, gloves and other apparatus of asimilar nature such as are commonly used in attaching or holding suchtools to the hand.

Other objects and advantages will be apparent from the followingspecification, taken in connection withthe accompanying drawings,wherein one form of the invention is illustrated. I

In the drawings Figure 1 is a plan view of a husking pin constructed inaccordancewith the presentinvention;

Fig. 2 is a side elevationof the pin, partly in section;

Fig. 3 is a sectional view, taken on the line 3-3 of Fig. 2; 7

Fig.4 is a sectional view,,also taken on the line 33 of Fig. 2,but'showing the movable portion of the handle in position to beadjusted;

Fig. 5 is a rearelevation of the tool; and

Fig. 6 is a fragmentary side elevation of modification. j

Referring more particularly to the drawings, the husking pin is shown ofsheet metal construction, and comprises the rolled longitudinallyextending staff or handle element 10, the latter terminating at one end1n an outwardly and laterally projecting husking finger 11, and anoutwardly and downwardly curved guard 12. Carried on the handle portion,and longitudinally adjustable thereon, when in a certain position, is asecond guard 13, the latter terminating at its inner end in a elongatedsleeve or collar 13 circumferentially corrugated, as at 13*; The handleportion 10 passes through the sleeve 13*, the latter together with theguard being longitudinally adjustable upon said portion. Thelongitudinal edges of the sleeve are spaced apart, as shown in thedrawings, in orderto provide for the passage therebetween of a pluralityof bosses or lugs l0 struck upon one side of the handle portion.

In assembling the two parts of the tool theguard 13 is slipped over theouter end of the handle portion 10 and moved inwardly thereon, so thattlielugs 10* are received between the edges of the sleeve. The guardisthen turned a half revolution upon the hairdle portion, during which thebosses engage the corrugations 13 and serve to hold the guard againstlongitudinal displacement, except that a slight longitudinal movement ispermitted at the end of said half turn to lock the two members againstrotation. This locking is preferably elfected by a small recess 13communicating with each of the annular grooves 13". The slightlongitudinal movement referred to draws the bosses or lugs 10 into saidrecess 13, thereby preventing relative rotation of the two parts.

This locking against relative rotation may be accomplished in variousother ways. j For example, the recess might be'replaced by holes in thesleeve. or holes might be provided" both in the handle 10 and thesleeve, through which a small pin might be inserted. A furtheralternative-would'be indentation, holes or notches in either the handleor the sleeve and struckup lugs in the other part so that one might snapinto the other and'resist turning when in use, the parts beingdisengagedpby twisting them with suflicient pressure, which pressurewould not be applied when the husker was inuse; A further alternative isthe provision of a wire, parts of which would engage the slit in thetubular member and other parts engage the spaced apart edges ofthesleeve, thereby locking against rotation. As will be appreciated, the

guard may be adjusted at any time by merely sliding the two parts towardeach other a fraction of an inch, and rotating one of them half arevolution in order to disengage the sleeve from the lugs or bosses,thus leaving the guard free to be moved in either direction along'thetubular portion until the desired position of adjustment has beenreached, at which time a half revolution 0% the guard upon the tubularportion and a slight longitudinal pull serves to lock the same again inits adjusted position and against displacement. a

The construction shown in part in Fig. 6 is the same as that shown inFigs. land 2, except that the recessesi3 are omitted. It is preferred inpractice to construct the lugs or bosses 1C of such size that theyengage the corrugations 13: with considerable friction, so that theguard in its various positions of adjustment will be substantiallyrigid.

As will be observed irom the drawings the front guard 12 curvesoutwardly and rearwardly' from the pin, while the rear guard 13 curvesoutwardly and forwardly therefrom. These guards, as wiil be appreciated,are' designed to receive the hand of the operator and, by reason oftheir configuration, serve to support the pin .on the hand, even thoughthe latter should be open. In other words, no actual gripping of thedevice is necessary to maintain the same in operative position. In theform of device shown in Fig. 6, the two parts may rotate on eahh otherslightly when the device is bein "used without danger of their becomingisengaged and ulling apart longitudinally. In practice t e guards arerelatively adjusted to accommodate the hand of thehusker, and so thatwhen applied to the hand the pin will be held transversely thereof alongsubstantially the line defined b the bases of the fingers. If desired,eacli guard may be apertured adjacent its outer end, as shown at 12" and13 respectively, so that a lacing of some sort may be employed acrossthe ends of the guards as a further precaution against displacement ofthe pin while in use. A further feature is the provision of the cuttingedge or notch 13 in either side of the guard 13. The edge is protectedfrom accidental contact with other objects by the restricted mouth ofthe notch. The usefulness of thiscutting edge will readily suggestitself to those skilled in the art.

Although I have shown and described my invention as being embodied incertain preferred forms, it will be understood that I do not desire tobe limited thereto unduly. On the contrary, I contemplate all properchanges in form, construction, and arrangement, the omission ofimmaterial parts, and the substitution of equivalents, as circumstancesmay suggest or necessity render expedient.

I claim- 1. A tool. of the class described comprising a tubular handleportion, a husking point, an outwardly and rearwardly curved guard, allof integral sheet metal construction, and a. second guard rotatably andadjustably mounted on said handle portion.

2. A tool of the class described comprising a hande portion, a huskingpoint, an outwardly and rearwardly curved guard, a sec ond guard carriedby said handle portion, and means whereby the same may be adjustedlongitudinally and laterally thereof.

3. A tool olf the class described compris ing a handle portion, ahusking point, an hutwardly and rearwardly curved guard, a

second guard carried by said handle por tion, said guard terminating ina corrugated sleeve at its inner end, said sleeve ad ustably engagingsaid handle portion, and means carried by said handle portion forengaging the corrugations ofsaid sleeve to prevent displacement.

4:. A tool of the class described comprisinca handle portion, a huskingpoint, an outwardly and rearwardly curved guard, a second guard carriedby said handle portion, said guard terminating in 5. corrugated sleeveat its inner end, said sleeve adjustably engaging said handle ortion,means carried byl said handle FONS/10H: for. engaging the corrugationsof said sleeve to prevent displacement, said guard being capable oflongitudinal adjustment with respect to said handle portion uponrotation of said sleeve -a fraction of a revolution.

5. A tool of the class, described compris ing a tubular handle portion,a huskin point, and a plurality of outwardly curved guards forengagement with the hand of the husker for holdin the tool in operativeposition thereon, one of said guards being adjustable bothlongitudinally and laterally with respect to the other.
